Sleep monitoring and regulation system based on phased array microphone

Abstract

The invention discloses a sleep monitoring and regulation system based on a phased array microphone. The system comprises a directional pickup unit which comprises an acoustic monitoring microphone phased array and a signal separation and extraction module, an intelligent analysis unit used for judging the respiration type of a monitored object according to a sleep respiration acoustic signal, obtained by the signal separation and extraction module, of the monitored object, and a personalized sleep aiding adjustment and sleep monitoring unit which comprises a respiration monitoring module, a loudspeaker microphone phased array, a sleep aiding module and an alarm module. According to the sleep monitoring and regulation system based on the phased array microphone, no load is applied to the human body, no-wearing sleep monitoring and regulation can be achieved, zero-load and personalized sleep monitoring and sleep regulation can be truly achieved, and the defect that an existing product is uncomfortable due to wearing is overcome; the sleep monitoring and judging precision can be improved; and personalized acoustic stimulation can be accurately given to the monitored object based on amonitoring result, so that sleep is promoted and the sleep quality is improved.

Description

technical field [0001] The invention relates to the technical field of sleep monitoring and regulation, in particular to a sleep monitoring and regulation system based on a phase array microphone. Background technique [0002] According to statistics from the World Health Organization, about 38% of the world's population suffers from sleep problems, and the quality of sleep directly determines people's physical and mental health, daytime cognitive function, and work efficiency. Long-term sleep disturbance will not only induce a variety of physical and mental diseases in individuals, but also bring a heavy economic burden to society. [0003] At present, the combination of subjective questionnaire and objective sleep monitoring is mostly used in sleep quality assessment and sleep disorder screening. Among them, polysomnography (PSG) is the only standard for diagnosing sleep disorders and systematically judging objective sleep conditions. It includes pressure airflow (snoring...

AI Technical Summary

Problems solved by technology

Among them, polysomnography (PSG) is the only standard for diagnosing sleep disorders and systematically judging objective sleep conditions. It includes pressure airflow (snoring) and thermal airflow, zRIP respiratory effort (chest / abdomen), body position, and SpO 2 The measurement of (pulse wave and pulse rate) is cumbersome to use, there is a sense of restraint, the sensor is easy to fall off, and zero-load sleep monitoring cannot be realized

Due to the expensive PSG equipment, the need for professional and technical personnel to operate, and the manual interpretation of the report is extremely time-consuming, the monitoring needs to be carried out in the hospital, which cannot reflect the real sleep status of the patient at home.

[0004] In addition, some current zero-load sleep monitoring products still have many problems, such as still need to wear related equipment, can not achieve true zero-load; monitoring accuracy is low

For sleep control, existing products such as head-mounted sleep monitoring equipment, smart mattresses, radar balls, and smart ventilators still have defects such as uncomfortable wearing and inability to truly achieve zero-load control.
